推荐答案

您可以使用 WakeLock 这样做:

You can do it using a WakeLock this way:

当您设置通知时:

WakeLock screenOn = ((PowerManager)getSystemService(POWER_SERVICE)).newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "example");
screenOn.acquire();

而且，重要，当您不再需要时释放唤醒锁:

And, IMPORTANT, release the wakelock when you don't need it anymore:

screenOn.release();
